Marsurf XR 20 Marwin Roughness Tester - 9205 FROM THE THUMBNAIL TEST... TO MARSURF

The latest information on MARSURF products can be found on our website: www.mahr.de, WebCode 158 Wherever surface structures influence the function, processing or appearance of components or products, careful testing is essential. But how can surfaces be tested? At the start of the 20th century, experts still had to test by eye and touch. A prac-ticed eye can detect features in the µm range, and even the much maligned thumbnail test delivered perfectly acceptable results. Now however, we live in an age of exchangeable parts, fits and internationalization, where subjective tests like this are no lon-ger adequate. Today, computer-aided measuring instruments provide objective data. Measurement and evaluation have become considerably easier. For decades, Mahr has been a worldwide pioneer in this area, as demonstrated by the company's numerous innovations and patented solutions in the field of roughness metrology. The interplay between the stylus, drive and measuring setup plays a key role in influencing the quality of surface measurement tasks. This is where Mahr's core expertise comes in. We have succeeded in perfecting the stylus method which is now widespread throughout the world. Thanks to the range of optical sensors offered by MarSurf, we can also meet the latest requirements for non-contact measurement, for example where ex tremely soft materials or ultra-short measuring times are involved. Developed with Mahr quality, expertise and know-how, MarSurf is the solution for all your surface metrology needs.
